Application filed November 1; 1924. Serial No. 747,330.

the-United States, residing, respectively, at

5 Washington, District of Columbia, and

Pittsburgh, in the county of Allegheny and I cer-.

State of Pennsylvania, have invente tain new and useful Improvements in Feed- 'ers'for In ot Molds, of

V v in feeders for ingot molds used in 'the manufacture ofiron-or steel'ingots and has for itsobject the prevention of holes and seams in the-upper end of the 'mg'ot known as fpip-ing and at the sameatime produce afeeder which will reduce segregation to aminimum.

Another object of. our "mvention is" to 2.0 provide a feeder made of tubular formf having -a perfectly plain exterior surface with no projection, whereby the feedermay extend -a greater or less distance into the mold, or either end placed within the bore of the mold and to provide means whereby the feeder is supported upon the upper end of. the mold.

i A further object of our invention is to provide a feeder of this character in which the outer face, at; its corners is provided with kerfs' adapted to receive supporting plates which 'restupon the upper end of the mold and .whereby the feeder is supported upon the mold in any of its'adjusted posi-- tions or .in its reversible position.

A still further object of our invention is to' provide a simple, cheap andeffective feeder of this character having certain details of structure and'combination of parts hereinafter more fully set forth. In the accompanying drawings;

Figure 1 is a perspective view of'a mold showmg our improved feeder supported therein. v p v t Figure 2 is a vertical transverse sectlonal view of Figure 1. Figure 3 is an enlarged horizontal sec- 'tional view of one corner of the mold showing our improved supporting plate in position.

Figure 4: 1s a perspective View of an Figure 5 is an enlarged horizontal seewhich the following; 1; mold.

tional view of one corner of the feeder showing the form of feeder and supporting means shown in Figure 4.

Figureti is a transverse vertical sectional view of a circular mold and feeder showing means whereby the feeder may be allowed to extend a greater or less distance into the mold or can be reversed with either end of the feeder within the bore ofthe ,I liigure 7 is a top plan view partly broken awa of Figure 6.

A Referring nowto the drawings, 1 repres'ents the mold and 2 the feeder. The feeder 2 as shpwn, is of a rectangular form having its outer face perfectly smooth and the exterior diameter of the feeder is slightly less than the'bore of the mold so that it can readily enter the same. offfthe feeder is provided with a kerf 3 which extends in two directions along the two side wallsextending from the corner. Placed in these kerfs are the angular supporting plates 4 preferably made of metal and which extend out beyond the kerf and rest upon the upper edge 5. of the -mold and whereby the feeder is supported within the upper end of the mold.

In the modificationshown in Figuresfi and 5 the kerfs-6 extend obliquely across the corner of the feeder? and the supporting plates 8 are of a-rectangular flat form arranged diagonally in respect to the walls of the feeder. a

In .the modification shown in Figure 6, the feeder 9 is of'a circular form and is provided withfour kerfs 10, 11, 12 and 13 oppositely arranged as clearly shown in Figure 7 of the drawings. there are a number of' these kerfs one above the other, in order that the feeder may be allowed to extend a greater or less distance into the bore of the mold. The supporting platesle are of acircular form having the flat edge 15 adapted to enter the kerfs 10, 11, 12. and 13 and extend out over the upper end of the mold and to support the feeder therein in the same manner as that referred to in the other forms.

Having thus fully described our invention what we claim is 3- 1. A feeder for ingot molds comprising a body portion having apertures at its corners and adapted to receive supporting means.

Each corner a In this form 2. A feeder for ingot molds comprising a body portion of refractory material having kerfs inits outer face for receiving supporting means.

3. A feeder for ingot molds'comprising a body portion of refractory material having kerfs for receiving supporting plates which extend over the upper end of the mold.

4. A feeder for ingot molds comprising a body portion of refractory material having kerfs arranged at the corners, and supporting plates entering said kerfs and extending outwardly over the upper end of the mold.

5. A feeder for ingot molds comprising a body portion of refractory material having kerfs at its corners and angular supporting plates entering said kei'fs and extending over the upper end ofthemold.

6. A feeder for ingot molds comprising a body portion of refractory material having kerfs in the four oppositely arranged Walls, and supporting and extending over the upper end ofthe mold.

7., A feeder for ingot molds comprising a body portion of refractory material having a series of rows of oppositely arranged kerfs, an supporting plates entering said kerfs and extending outwardly over the upper end of the mold.

In testimony whereof we afiix our signatures.
